RESILIENT SNAP FASTENER ELEMENT Filed Sept. 27, 1928 Patented Nov. 17,1931 UNITED stares PATENT orrica PAUL E. FENTON, OF THCMASTON,CONNECTICUT, ASSIGNOR TO SCOVILL MANUFAC- TURING COMPANY, OF VJATERBURY,CONNECTICUT, A. COBPORATON 0F CONNECT- ICUT RESILENT SNAP FASTENERELEMENT Application filed September 27, 1928. Serial No. 3055,828.

The object of this invention is to provide a sturdy, long-lived snapfastener element, preferably a socket.

In the specitic illustration of the invention herein explained, theinvention consists ot a socket having an outer rim and an inner rim,both ot Which are rigid or non-resilient, and an integral intermediateconnection projecting from the adjacent edges of lthe rims, in the formoit an outer Wall .and an inner Wall, the inner Wall being slottedlongitudinally so as to impart a degree ot' resilience to the article,the slots extending short ot the edge ot the inner rim, the inner rimbeing perforated to receive and to beV engaged by a suitable setting orattaching element, as I will proceed now to explain more fully andlinally claim.

In the accompanying` drawings illustrating the invention., in theseveral figures of which like parts are similarly designated, Figure 1is a top plan view, and Fig. 2 is a vertical section ot one form otresilient socket embodying` the invention. Fig. 3 is a vertical sectionillustrating a snap fastener couple attached to parts to be fastened,the socket element showing the present invention.

The resilient snap fastener element ot this invention is the same asthose disclosed in my applications Filed Septemberli. 1928, Serial Nos.305,191 and 305,192, excepting that only the inner Wall is slottedinstead ot both Walls; .and it diiiers from the device of my applicatontiled September 2T, 1923, Serial No. 308,829, patented ctober 22, 1929,No. 1,732,837, in that its inner Wall only is slotted. The outer rim l,and the inner rim 2, lie in substantially the same plane, with theintermediate rim-connecting` material eX- tending therefromsubstantially normal thereto, and bent to torm the outer vvall 3 `andthe inner Wall 4i. These Walls are bowed, knurled or curved at 5 and 6,respectively, to provide surfaces adapted to the complemental stu d 7,to eiiect'a union of the snap fastener couple, as illustrated in Fig. 3.

VThe'innerV Wall Ll, is slotted at 8, trom the top toward but notthrough the inner rim 2; or the slots may extend short ot the rim Theseslots may extend into the meeting portions of the outer and inner Walls,as herein shown.

The inner rim 2, has a central perforation 9, to receive and be engagedby a capped eyelet 10, the barrel of which is clinched therein,

as shown in Fig. 3, to set or attach the element; but the invention isnot limited to the means for setting or attaching, nor to any particularform of stud.

The part 11 may represent one portion ofi an article to be fastened, onwhich the socket is set, and the part 12 may represent the other portionon which the stud is set.

As shown in Fig. 3, the stud 7 has an outer rim 13, an inner rim 14 anda connecting Wallk 15, all of which parts are rigid; and the attachingpost or rivet 16 by which the stud is attached to the part 12, is passedthrough the part 12 and an opening in the rim 14 and clinched therein.

The two rims, 1 and 2, and their connect- .ing Walls 3 and 4, are in oneunitary piece,

thus eiiecting economy in construction and possessing greatlsturdiness.rIhe outer Wall acts as an auxiliary unit Vto the inner Wall inproviding a long-lived snap action; and it also provides a support forthe inner resilient Wall which prevents crushing under the damagingeii'ects of laundering.

The slotting ot the inner Wall effects a breaking down ot the rigiditvot that partie* ular Wall and serves to provide some resiliency, andthis is backed up by the opposite nonresilient outer Wall serving as anauxiliary.

The proven fact is that a very few thousandths of an inch of givefurnishes the necessary resilient action. It is possible, also, that thesolid metal is weakened by the inclusion ot the slots just enough topermit a inner wall being slotted longitudinally from the bend, and theouter Wall left solid.

2. A resilient snap Jastener element, made in one. unitary piece, andhaving an outer rim and an inner rim, and an outstanding connectionnormal to the rims and bent to forni an outer wall and an inner Wall,the inner Wall being slotted longitudinally from the bend, and the outerWall unslotted, the inner rinr having` an openingl to receive and beengaged by an attaching' device.

En testimony WhereolE I have hereunto set my hand this 26th day ofSeptember, A. D. 1928.
